Making It Functional

Learn how to serve multiple pages with the HTTP server.

We'll cover the following...

Creating the page for a restaurant

Let’s create a restaurant menu page where we can add food to our cart. Let’s also modify our main page so that we are shown the restaurant page when we click on a food type.

const http = require("http");
const fs = require("fs");

const hostname = "0.0.0.0";
const port = 3500;

const homePage = fs.readFileSync("main.html");
const aboutPage = fs.readFileSync("about.html");
const menuPage = fs.readFileSync("menu.html");
const css = fs.readFileSync("styles.css");

const server = http.createServer((req, res) => {
  res.statusCode = 200;
  if (req.url == "/") {
    res.statusCode = 200;
    res.setHeader("Content-Type", "text/html");
    res.write(homePage);
  } else if (req.url == "/about") {
    res.statusCode = 200;
    res.setHeader("Content-Type", "text/html");
    res.write(aboutPage);
  } else if (req.url == "/menu") {
    res.statusCode = 200;
    res.setHeader("Content-Type", "text/html");
    res.write(menuPage);
  } else if (req.url == "/styles.css") {
    res.statusCode = 200;
    res.setHeader("Content-Type", "text/css");
    res.write(css);
  } else if (req.url.match(/images/g)) {
    try {
      res.statusCode = 200;
      res.setHeader("Content-Type", "image/jpeg");
      imgLoc = req.url.replace("/", "../");
      image = fs.readFileSync(imgLoc);
      res.end(image);
    } catch {
      res.statusCode = 404;
      res.write("404");
      console.log(req.url);
    }
  } else {
    res.statusCode = 404;
    res.write("404");
    console.log(req.url);
  }
  res.end();
});

server.listen(port, hostname, () => {
  console.log("Server is now running");
});
